/* initramfs_data includes the compressed binary that is the filesystem used for early user space. Note: Older versions of "as" (prior to binutils 2.11.90.0.23 released on 2001-07-14) dit not support .incbin. If you are forced to use older binutils than that then the following trick can be applied to create the resulting binary: ld -m elf_i386 --format binary --oformat elf32-i386 -r \ -T initramfs_data.scr initramfs_data.cpio.gz -o initramfs_data.o ld -m elf_i386 -r -o built-in.o initramfs_data.o For including the .init.ramfs sections, see include/asm-generic/vmlinux.lds. The above example is for i386 - the parameters vary from architectures. Eventually look up LDFLAGS_BLOB in an older version of the arch/$(ARCH)/Makefile to see the flags used before .incbin was introduced. Using .incbin has the advantage over ld that the correct flags are set in the ELF header, as required by certain architectures. */ #include #include .section .init.ramfs,"a" __irf_start: .incbin __stringify(INITRAMFS_IMAGE) __irf_end: .section .init.ramfs.info,"a" .globl VMLINUX_SYMBOL(__initramfs_size) VMLINUX_SYMBOL(__initramfs_size): #ifdef CONFIG_64BIT .quad __irf_end - __irf_start #else .long __irf_end - __irf_start #endif mp-back net-next plumbingsTobias Klauser

HID: cp2112: fix sleep-while-atomic
A recent commit fixing DMA-buffers on stack added a shared transfer buffer protected by a spinlock. This is broken as the USB HID request callbacks can sleep. Fix this up by replacing the spinlock with a mutex.
